12.6 fractal image Compression
Fractal encoding is a mathematical process used to encode bitmaps containing a real-world image
as a set of mathematical data that describes the fractal properties of the image. Fractal encoding
relies on the fact that all natural, and most artificial, objects contain redundant information in the
form of similar, repeating patterns called fractals.
12.6.1 fractal Basics
A fractal is a structure that is made up of similar forms and patterns that occur in many different
sizes. The term fractal was first used by Benoit Mandelbrot to describe repeating patterns that
